Alphabetical Terms and Definitions Specifically Related to Paper Manufacture



The Primary application of Glassine is it’s Translucent / See Through use, permitting viewing without exposing the

contents to fingerprints, abrasive materials or other contaminants. The Paper Material is porous and allows for chemical

fume and moisture dispersal preventing the degradation of the contents.

With all the corrosive materials around us from cleaning solvents to the airborne abrasive materials in dust form, we

sometimes need a little special protection for those items that need that little extra care. The US Postal Service has long recognized the importance of the Glassine Envelope for long and short term storage of delicate and valuable stamps.

Coin collectors will confirm that as well. For the most part, Glassine Paper is made from the finest unbuffered, unbleached, acid free, pH neutral, 100% pure pine wood cellulose and Archival quality materials.. Assuring maximum visibility, in a number of varieties of sizes and styles, that will help protect their contents from contaminants and abrasive materials that can damage those special items and not chemically react with or harm rare collectable stamps, coins, delicate old or new photographs, antique negatives or transparencies, electron microscope negatives or plates, laboratory specimen collections, such as crime scene investigations, entomology studies and even mushroom spore samples as well as other hobbies. Not all is pH neutral and a lot is intended for grease proof uses where oil is used for cooking and storage. Even more is used for silicone filming, for use as a backing for self sticking labels such as stamps and shipping labels. The most commonly used weights are  #22, #25, #30, #35, #40 and #60 pound translucent paper stock. The #35 is a specifically preferred weight for Postal Services use with Postage Stamps. Glassine is an excellent choice for the home, shop, office, business and research laboratory facility or even specialty weddings and wrapping decorative items or confections. Ideal for food packaging needs, Glassine Lined bags provide a barrier for moisture, grease and stains. Made of 30 lb. Paper, available in decorative colors with an inner 25 lb. Glassine liner.

Some not so well known uses include Medical and Laboratory sterilizing, biological indicator safety testing and chemical baths. The primary use of the Medical Blue paper is because it is a typical medical and laboratory related color and more specifically, it holds it’s color after autoclaving while the Bleached White envelopes tend to turn yellow. There is definitely an aesthetic value to the Med-Blue paper. Green is also used, primarily for weight scale paper, but the blue is mainly used for the medical profession.
